View source for DAP metadata display failure

==The problem==
Your [http://en.wikipedia.org/wiki/Digital_audio_player DAP] labels your MP3 files 'Unknown' or otherwise fails to show the tag data - title, artist etc.

==The probable cause==
Your files' tag data is in ID3V2.4 and/or UTF format, which few DAPs recognise. Most DAPs recognise the format ID3v2.3 ISO-8859-1 .

==The solution==
Convert your files' tag data to ID3v2.3 ISO-8859-1 format as follows:

#Go [http://www.mp3tag.de/en/download.html here] to download [[Mp3tag]] V2.39f or later, install and launch.
#Click Tools, Options, Tags Mpeg and ensure that under Write, '''ID3v2.3 ISO-8859-1''' is selected.
#Click OK.
#Click File | Change Directory and select the directory contaning your music files.
#Click Edit | Select All Files, then File | Save tag .
#Click File | Exit

Now resend your files to your DAP. Your DAP should show the titles, artist etc. as required.
